SPECIFICATION forming part of Letters Patent No. 760,591, dated May 24, P1904:.

Appiication ned september 8,1902. serai No. 122,478. cammina To all whom t may concern'.-

N Be it known that I, ERNEST P. WARNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and ,useful Improvement in Fan-Motor Supports, of which the following is a full, clear, concise, andeXact description.y f

My invention relates to a fan-motor support, and has for its object to provide a simple structure by which the fan may be directed up or down or toward either side and securely clampedin any of its positions of adjustment.

My invention will be described by reference tothe accompanying drawings, in whichyFigure 1 is a View in elevation of an electric fan equipped with my improved Support'. Fig. 2 is a view showing the same fastened to a'wall.

Fig. 4 is a detail sectional view of an adjustable ball-and-socket joint by which the Inotor-frame is connected to the supporting-base, and Fig. 5 is a detail sectional view of the hollow ball portion of the ball-and-socket joint at right angles tothe section thereof shown in Fig. 4;.

Similar letters of reference are usedv to designate the same parts wherever they are shown.

4 Thebase or supporta, which may be adapted to rest upon a table, as shown in Fig.Y 1, or fastened to a wall, as shown in Fig. 2, is provided with a portion c, adapted to form' the clamping-bolt e.

socket of a ball-and-socket joint, the ball portion whereof carries the frame d of the 'fanmotor. The ball portion b is-hollow, as shown in Figs. 4L and 5, and is provided witha hole b', through which is passed the shank of a The head of the clampingbolt is formed with a bearing-su rface e', which may be of-spherical curvature, fitting.` the concave inner surface of the ball and the hole b is considerably larger thanthe shank e of the bolt, thus allowing the motor-frame carried by the ball not only to be rotated'com- Fig. 3 isa detail view of the support.

pletely aroundy the bolt e as an axis, but also to be tipped considerably in any direction,v

giving the characteristic advantages of adjustment of the ball-and-socket joint. A clamping-nut f is provided for the shank of the bolt e, which projects through the socket c,- whereby the head e of the bolt may be drawn tightly against the inner surface of thev hollow ball b to clamp the ball and the motorframe supported thereby in any position of adjustment.

Having described my invention, I claim- 1. In a fan-motor support, the combination l with the baseahaving the socket c, of the hollow ballb resting in said socket and carrying the motor-frame 0l, theI clamping-bolt e passing throughthe ball and socket and having a head bearing upon the inside of the hollow ball, the circular hole in said ball through which the bolt passes being enlarged, and the clamping-nut f on the shank of said bolt projecting through the socket, adapted to draw the head of the bolt against the inner wall of the hollow ball.

2. In a fan-motor support, the combination rwith the base a and the motor-frame d, of a ball and-socket joint uniting the same, said joint comprising the socket c, the hollow ball resting vin said socket, the'clamping-bolt e passing through the ball and socket and having ahead bearing upon the inside of the hollow ball, the circular hole in said ball through which the bolt passes being considerably larger than the shank of said bolt, and the clamping-nut f on the shank of said bolt projecting through the socket adapted to draw the head of the bolt against the inner, wall of the hollow ball.

In witness whereof VI hereunto subscribe my name this7 th day of July, A.- D. 1902.

ERNEST P. WARNER.
